Trick 6: Creating Organic-Looking Objects Using Photoshop Filters

Fractal math, when plotted to the screen, can be an absolutely wonderful thing. There is no simple way to describe fractal math (at least not in this book), except to say that fractals are so complex that they cannot be plotted with a mere curve. Fractals are a seemingly random set of fluctuations that apparently cannot be represented by an equation. But many fractals are generated through simple mathematical equations.

Fortunately, we are artists, not mathematicians, so if you really want to make your head ache, read some of the work by Professor Ken Perlin (I mean this in a good way, Ken) at NYU who, along with Ken Musgrave (who helped re-engineer Bryce), is active on the Terragen discussion list. These men understand the self-similarity of fractals and the reasons they most often look like a coastline, a dinosaur hide, or other organic matter. And that's precisely what we're looking for in this trick: How do you make organic-looking stuff using Photoshop?
